High-sensitive troponin T is associated with all-cause and cardiovascular mortality in stable outpatients with type 2 diabetes (ZODIAC-37)

Background We aimed to investigate whether high-sensitive cardiac troponin T (hs-cTnT) is associated with all-cause and cardiovascular mortality in stable type 2 diabetes (T2D) outpatients treated in primary care. Methods Cardiac troponin T was measured with a high-sensitive assay at baseline in patients with T2D participating in the observational ZODIAC study. Cox proportional hazards models were used to investigate the relationship between hs-cTnT and mortality with adjustment for selected confounders. Risk prediction capabilities of hs-cTnT were assessed with Harrell C statistics. Results Complete baseline data were available for 1,133 patients. During median follow-up of 11 (7-14) years, 513 (45%) patients died, of which 218 (42%) died of cardiovascular causes. Of the patients with undetectable hs-cTnT levels (
